Improved bilinears in unquenched lattice QCD
Tanmoy Bhattacharya, Rajan Gupta, Weonjong Lee +2
We summarize the extent to which one can use Ward identities to non-perturbatively improve flavor singlet and non-singlet bilinears with three flavors of non-degenerate dynamical W…
Status of B_K from Lattice QCD
Rajan Gupta
A brief review of lattice calculations of the bag parameter B_K relevant for understanding indirect CP violation in the neutral kaon sector is given. A status report on current sta…
Order a improved renormalization constants
Tanmoy Bhattacharya, Rajan Gupta, Weonjong Lee +1
We present non-perturbative results for the constants needed for on-shell improvement of bilinear operators composed of Wilson fermions. We work at and 6.2 in the qu…
Fixed-point pure gauge action using RGT
Tanmoy Bhattacharya, Rajan Gupta, Weonjong Lee
We present a status report on the construction of the classical perfect action using the renormalization group transformation (RGT). We investigate finite volume cor…
Order a improved renormalization constants
T. Bhattacharya, R. Gupta, W. Lee +1
We impose the axial and vector Ward identities on local fermion bilinear operators in the Sheikholesalami-Wohlert discretization of fermions. From this we obtain all the coefficien…
General Physics Motivations for Numerical Simulations of Quantum Field Theory
Rajan Gupta
In this introductory article a brief description of Quantum Field Theories (QFT) is presented with emphasis on the distinction between strongly and weakly coupled theories. A case…
